Abstract

A driver for engaging an endcap of an intramedullary nail. The driver includes a handle extending along a longitudinal axis of the driver from a proximal end to a distal end. The handle having a handle channel extending longitudinally therethrough. The driver also includes a shaft extending through the handle channel from a proximal end to a distal end along the longitudinal axis. The shaft having a shaft channel extending longitudinally therethrough. The distal end of the shaft extends distally from the handle. The distal end of the shaft forms a driving element to be inserted into a head portion of the endcap. The driver further includes a retention pin slidably received in the shaft channel. The retention pin extends also extends along the longitudinal axis. The distal end of the retention pin is configured to reversibly lock the shaft to the head portion of the endcap.
